AUTOMOBILE-RADIATOR.

' ject of the Emperor of Austria-Hungary,

residing at Cleveland, in. the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Automobile-Radiators, of which the following is a specification.

This invention relates to radiators particularly adapted for automobile use, and comprises especially a new and improved construction of the radiator tubes, which are arranged vertically for the purpose of conducting the water between upper and lower headers, with air passages and heat-diffusing flanges or members between the tubes.

The respective tubes are formed by means of two sets of plates which, when assembled, produce a plurality of water passages between the plates, together with supporting and radiating elementswhich space the tubes or plates apart and which assist in making the structure rigid.

The invention is illustrated in the accompanying drawings, in which Figure l is a front elevation of the complete radiator. Fig. 2 is a horizontal section of a part thereof. Fig. 3 is a vertical section of the lower part thereof. Fig. 4 is an enlarged detail in front elevation of part of the radiator structure. Fig. 5 is a detail in section showing the lower connection of the tubes to the header.

Referring specifically to the drawings, 6 indicates the upper header and 7 the lower header. The radiator structure comprises two sets of similar plates bent to substantially zigzag form, and arranged in pairs, these plates being indicated at 20. The plates of each pair are placed in contact and are soldered or otherwise secured together, and at the angles of the plates tubes are produced by means of the outer bends 8 on one plate and the inner bends 9 on the other. These bends are arranged alternately in each plate, and are substantially semi-circular in shape or outline, the parts 8 being the normal or outer curve of the bends, and the parts 9 being reversed or reia'ntering curves, so that when the plates are put to gether the parts 8 and 9 produce complete vertical tubes therebetween, located at the corners of the corrugations in the plates. The intermediate parts of the plates fit together closely and are preferably perforated- Specification of Letters Patent.

as indicated at 13 to provide air passages through the same.

The pairs of plates are spaced apart, so that a1r pas sages are provided between each pair, sa1d air passages communicating with each other through the openings 13. The intermediate or straight parts of the plates, between the tubes, form in effect radiating flanges extending vertically along the tubes, and exposed on opposite sides to the air currents, which in consequence of the shape of the plates flow in a zigzag ortortuous course through the radiator. At the vertical edges of the plates they are joined by a lap-joint formed by a flange 10 bent or crimped over the edge 11 of the adjacent plate and brazed or soldered together. The tubes are connected to the headers by means of nipples 14;, shown in Fig. 5, which project into the ends of the tubes.

To give a greater radiating surface, and to strengthen the structure, spacing strips 12 extend across the air passages and between the tubes. These supports are conveniently formed by bending a'metal strip back and forth, as shown in Fig. 1, with horizontal parts extending across the passages, and with vertical parts resting against the tubes, and the horizontal parts are preferably so spaced that'they extend between the holes 13-, whereby the air currents flowing through said holes are not obstructed.

As shown in Fig. 2, the tubes stand in zigzag rows from front to back, and in alined rows transversely, and obviously the dimensions and the number of the tubes can be varied according to the size of the radiator desired.

The invention is not limited to the exact embodiment shown, but may be varied in many particulars, within the scope of the' following claims. Thus the cross supports 12, and the openings 13, may be omitted.

continuous tubes extending between the headers. Y

2. A tube structure for ra'diators, comprising corrugated plates side by side, each of which has alternate convex and concave curved parts at the corners of the corrugations, said parts forming tubes.

3. A tube structure for radiators, comprising a pair of zigzag plates with their sides in contact, each plate having, at the corners of the corrugations, alternate convex and concave curved parts which fit together to form complete tubes, with intermediate flat portions between the tubes.

4. A radiator structure comprising corrugated plates with their sides together to form a plurality of spaced passages therebetween, and having openings through the same, between said passages.

5. A radiator structure comprising corrugated plates set together and bent to form spaced passages at the corners of the corrugations, with intervening straight portions havirlg air openings through the same.

6. radiator structure comprisingcorrugated plates set together and bent to form spaced passages at the corners of the corrugations, with intervening straight portions having air openings through the same and spacers extending between the plates and located between said air openings.

In testimony whereof, I afiix my signature in presence of two witnesses.
